<p>At least one of a DX geothermal refrigeration system design, a reverse-cycle DX geothermal heat pump system design, a DX geothermal cooling mode only system design, and a DX geothermal heating mode only system design, which utilize the sub¬ surface geology with a grouted well as a heat sink in the cooling/refrigeration mode, and as a heat source in the heating mode; with an optional air-source high level heat sink for use in the refrigeration mode; with optional multiple sub-surface larger sized vapor refrigerant lines, as well as with a super-efficient vacuum insulation design for relevant sub-surface refrigerant transport tubing, and with an optional specially designed electronic expansion valve.</p> |
